AlphaStation is the name given to a series of computer workstations, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP. As the name suggests, the AlphaStations were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaStations comprise Tru64 UNIX (formerly Digital UNIX), OpenVMS and Windows NT (with AlphaBIOS ARC firmware). Most of these workstations can also run various versions of Linux and BSD operating systems.

Models
